Big Red Oaks 4 me
Fun with flying wood chips
If you like the power head, and the bar is ok, nothing will beat a new chain.
My bet is, those are dremmeled.

Or give it to someone that knows how to file.........I would agree with the try a NEW Chain suggestion, see how the saw does with that, then evaluate if the current chain is worth the effort to salvage.

You are kind....... I was going to suggest they had been hit with a 4.5"grinding disc!
That's why I said that suggestion was too kind- I would near put money on the fact those rakers have been hit with an angle grinder!I always use my die grinder on my rakers and a file and file guide on the teeth. I use the raker gauge to check the height but I do use a die grinder to lower them when needed. I've never had a flat file last very long so I chose the die grinder for the rakers.
That's not the issue herePlease tell me you didn't grind that chain to death trying to make all the teeth the same legnth...
That could be part of the issue . . .This was sharpened on an HF grinder . . .

Look at the reflected light off of the top plate edge, side plate edge, and rounded corner (semi-chisel cutter). These indicate that they are not sharp.

Compare the depth gauge profiles to the illustration of a new cutter. The high point touches the wood, but if too sharp, or too rough, it can dig in. When cutters get worn, filed, ground back as far as yours are, they might also need additional offset (say 0.030" instead of 0.025"). Some guys will use an angular depth gauge too (e.g 'File-O-Plate' or Husqvarna tool); others will just take a few more swipes with the file. But the profile is important too.
Harbor Freight grinder can be OK for just touching up cutters, but is not a good tool for reshaping them.

The grinding wheels are of different widths for 3/8 lp, .325, 3/8 and .404. The wrong wheel won’t give correct specs on the cutter.Maybe the disc in that sharpener doesn't like 3/8"?
This is after the saw cut a bit in that dead hard maple crotch. So it's duller than when it first came off the grinder. But either that wood didn't want to be cut or that chain wasn't sharp (or both). I don't have a sharp 7/32 file to finish after the grinder so off the grinder is my only choice. I do have an old dull one. Probably would be good enough to touch up the edges after the HF chainsaw sharpener.
I like the HF sharpener on rocked chains (esp full chisel) since it takes forever to get the tooth back 1/32" to a square edge. I usually have results that throw chips though. Maybe the wheel in that sharpener doesn't like 3/8"? Maybe I need to dress or get a new wheel? My tooth length is consistent so I think I apply pressure evenly per tooth.

I hate dull files. Like dull sandpaper - need to get tossed.Yep, because nothing cuts quite like an old dull file.

This was done on an HF sharpener. Also it had been run 10 minutes in that dead sugar maple before pic. And no I wasn't saying the dull old 7/32 file was preferable. I said since 3/8" chain is new to me and it's the only 7/32 file I own, maybe it would be enough to pickup where the HF wheel left off. If you have anything constructive or should I say "to add" to the thread please do. I already know there's a problem. Criticism and pointers are welcomed; sarcasm not needed.

Listen to Philbert and hsell or throw that chain out and get new, simple stuff.You’ve been given sound advice: take it.
